The attachment of accelerometers is typically accomplished by magnetic mount, wax,_x000D_
glue, screw-mount, or a hand-held technique. This paper present the results of careful_x000D_
laboratory study of the resulting accuracy of the vibration values across a broad frequency_x000D_
spectrum, based on both impact testing as well as shaker testing in a laboratory environment._x000D_
The magnetic mount and had-held techniques are much more convenient than attachment_x000D_
with screws or glue, but have been shown in various studies to result in tapping on_x000D_
uneven surfaces, and in general to lose frequency response above 500 Hz, at frequencies_x000D_
still very much of interest in machinery diagnostics. This is detailed in ISO 5348. _x000D_
However, the authors demonstrate that the combined use of wax with either the _x000D_
magnetic mounting technique or the hand-held method can provide surprisingly accurate _x000D_
readings for most practical applications.
